FIELD OF THE INVENTION

This invention is in the field of corn breeding. Specifically, thepresent invention provides a maize plant and its seed designatedKDC5164, MIJ6800, MFF7398, or MFX7761, as well as derivatives andhybrids thereof.

BACKGROUND OF THE INVENTION

Maize (or corn; Zea mays L.) plant breeding is a process to developimproved maize germplasm in an inbred or hybrid plant. Maize plants canbe self-pollinating or cross pollinating. Self pollination for severalgenerations produces homozygosity at almost all gene loci, forming auniform population of true breeding progeny, known as inbreds. Hybridsare developed by crossing two homozygous inbreds to produce heterozygousgene loci in hybrid plants and seeds. In this process, the inbred isemasculated and the pollen from the other inbred pollinates theemasculated inbred. Emasculation of the inbred can be done by chemicaltreatment of the plant, detasseling the seed parent, or the parentinbred can comprise a male sterility trait or transgene impartingsterility, eliminating the need for detasseling. This emasculatedinbred, often referred to as the female, produces the hybrid seed, F1.The hybrid seed that is produced is heterozygous. However, the grainproduced by a plant grown from F1 hybrid seed is referred to as F2grain. F2 grain which is a plant part produced on the F1 plant willcomprise segregating maize germplasm, even though the hybrid plant isheterozygous.

Such heterozygosity in hybrids results in robust and vigorous plants.Inbred plants on the other hand are mostly homozygous, rendering themless vigorous. Inbred seed can be difficult to produce due to suchdecreased vigor. However, when two inbred lines are crossed, theresulting hybrid plant shows greatly increased vigor and seed yieldcompared to open pollinated, segregating maize plants. An importantconsequence of the homozygosity and homogeneity of inbred maize lines isthat all hybrid seed and plants produced from any cross of two suchlines will be the same. Thus the use of inbreds allows for theproduction of hybrid seed that can be readily reproduced.

There are numerous stages in the development of any novel, desirableplant germplasm. Plant breeding begins with the analysis and definitionof problems and weaknesses of the current germplasm, the establishmentof program goals, and the definition of specific breeding objectives.The next step is selection of germplasm that possess the traits to meetthe program goals. The aim is to combine in a single variety an improvedcombination of desirable traits from the parental germplasm. Theseimportant traits may include, for example, higher yield, resistance todiseases, fungus, bacteria and insects, better stems and roots,tolerance to drought and heat, improved nutritional quality, and betteragronomic characteristics.

Choice of breeding methods depends on the mode of plant reproduction,the heritability of the trait(s) being improved, and the type ofcultivar used commercially (e.g., F1 hybrid cultivar, pure linecultivar, etc.). For highly heritable traits, a choice of superiorindividual plants evaluated at a single location may be effective,whereas for traits with low heritability, selection can be based on meanvalues obtained from replicated evaluations of families of relatedplants. Popular selection methods commonly include pedigree selection,modified pedigree selection, mass selection, and recurrent selection.

The complexity of inheritance influences the choice of breeding method.Backcross breeding is used to transfer one or a few favorable genes fora highly heritable trait into a desirable cultivar. This approach hasbeen used extensively for breeding disease-resistant cultivars andintroducing transgenic events into maize germplasm. Thus, backcrossbreeding is useful for transferring genes for a simply inherited, highlyheritable trait into a desirable homozygous cultivar or inbred linewhich is the recurrent parent. The source of the trait to be transferredis called the donor parent. After the initial cross, individualspossessing the phenotype of the donor parent are selected and repeatedlycrossed (backcrossed) to the recurrent parent. The resulting plant isexpected to have the attributes of the recurrent parent (e.g., cultivar)and the desirable trait transferred from the donor parent.

Each breeding program generally includes a periodic, objectiveevaluation of the efficiency of the breeding procedure. Evaluationcriteria vary depending on the goals and objectives, but should includegain from selection per year based on comparisons to an appropriatestandard, overall value of the advanced breeding lines, and number ofsuccessful cultivars produced per unit of input (e.g., per year, perdollar expended, etc.).

The ultimate objective of commercial corn breeding programs is toproduce high yield, agronomically sound plants that perform well inparticular regions of the U.S. Corn Belt, such as a plant of thisinvention.

It also refers to both the natural and artificialtransmission of a desired allele, transgene, or combination of desiredalleles of a genetic locus or genetic loci, or combination of desiredtransgenes from one genetic background to another. For example, adesired allele or transgene at a specified locus can be transmitted toat least one progeny via a sexual cross between two parents of the samespecies, where at least one of the parents has the desired allele ortransgene in its genome. Alternatively, for example, transmission of anallele or transgene can occur by recombination between two donorgenomes, e.g., in a fused protoplast, where at least one of the donorprotoplasts has the desired allele in its genome. The desired allele maybe a selected allele of a marker, a QTL, a transgene, or the like.Offspring comprising the desired allele or transgene can be repeatedlybackcrossed to a line having a desired genetic background and selectedfor the desired allele or transgene, with the result being that thedesired allele or transgene becomes fixed in the desired geneticbackground.

I. Embodiments of the Invention

A. Inbred and Hybrid Production

Certain regions of the Corn Belt can have specific difficulties relatedto grain production that other regions may not have. Thus, the cornhybrids developed from inbreds should have traits that overcome or atleast minimize these regional growing problems. Examples of theseproblems include Gray Leaf Spot infection in the eastern Corn Belt, cooltemperatures during seedling emergence in the northern Corn Belt, CornLethal Necrosis (CLN) disease in the Nebraska region and soil withexcessively high pH levels in the west. Hybrid combinations employinbreds that address these specific issues resulting in the developmentof hybrids which are well adapted to niche production challenges.However, the aim of seed producers is to provide a number of traits toeach inbred so that the corresponding hybrid combinations can be usefulacross broad regions of the Corn Belt. Biotechnology techniques offertools, such as microsatellites, SNPs, RFLPs, RAPDs and the like, tobreeders to accomplish the goal of providing desirable traits ininbreds.

To produce hybrids, inbreds are developed using numerous methods, whichallow for the introduction of needed traits into the inbreds used in thehybrid combination. Hybrids are not often uniformly adapted for usethroughout the entire U.S. Corn Belt, but most often are adapted forspecific regions of the Corn Belts because for example, northern regionsof the Corn Belt require shorter season hybrids than do southernregions. Hybrids that grow well in Colorado and Nebraska soils may notflourish in richer Illinois and Iowa soils. Thus, several differentmajor agronomic traits are important in hybrid combination for growth inthe various Corn Belt regions, and these traits have an impact on hybridperformance.

If there is a pool of desirable maize varieties for use as parents thendevelopment of a corn hybrid involves one step crossing the selectedmaize variety with at least one different maize variety to produce thehybrid progeny. This single crossing step is possible because breedershave been developing inbreds from different maize germplasm pools sincethe early 1900s, which can be used in hybrid combinations. However, tokeep producing better and higher yielding hybrids, better inbreds mustbe developed. Inbred development involves the step of selecting plantsfrom various germplasm pools, or from the same germplasm pool for makinginitial breeding crosses; and then either producing haploid seed fromthe cross and selfing as needed, or selfing the breeding crosses forseveral generations to produce a series of inbred lines, which, althoughdifferent from each other, breed true and are highly uniform. Duringplant selection in each generation, uniformity of plant type ismaintained to ensure homozygosity and phenotypic stability. Aconsequence of the homozygosity and homogeneity of the inbred lines isthat the hybrid between a defined pair of inbreds, regardless of themethod by which the inbreds were produced, will always be the same.

The maize variety and seed of the present invention can be employed tocarry an agronomic package of this invention into a hybrid.Additionally, as described herein the inbred line can comprise one ormore transgenes that are then introduced into the hybrid seed. When themaize variety parents that give a superior hybrid have been identified,the hybrid seed can be reproduced indefinitely as long as thehomogeneity of the maize variety parents is maintained.

Any breeding methods using the maize variety KDC5164, MIJ6800, MFF7398,or MFX7761, and its progeny are part of this invention. Inbreddevelopment can be accomplished by different methods, for example,pedigree selection, backcrossing, recurrent selection, haploid/doubledhaploid production. An inbred plant with similar genetic orcharacteristics to maize variety KDC5164, MIJ6800, MFF7398, or MFX7761could be produced by applying double haploid methods to the progeny of across between maize inbred KDC5164, MIJ6800, MFF7398, or MFX7761 and adifferent plant. Double haploid methods produce substantially homozygousplants without repeated backcrossing steps. The haploid/doubled haploidprocess of developing inbreds starts with the induction of a haploid byusing, for example, KWS inducers lines, Krasnador inducers lines, stocksix inducer lines (Coe, 1959, Am. Nat. 93:381-382). The haploid cell isthen doubled, and the doubled haploid plant is produced. In someembodiments, a method of producing an maize plant with doubled haploidchromosomes derived from the maize variety KDC5164, MIJ6800, MFF7398, orMFX7761 the method comprising: (a) crossing a plant, wherein said plantmay have one or more traits, with an inducer maize plant to produce aprogeny with haploid chromosomes; and (b) doubling the haploidchromosomes in the progeny to produce a maize plant with doubled haploidchromosomes. In some embodiments, the progeny may be for example a cell,seed, embryo or plant. In further embodiments, the maize plant withdoubled haploid chromosomes produced by step (b) above is a maize inbredplant with the characteristics of maize variety KDC5164, MIJ6800,MFF7398, or MFX7761. In other embodiments, the plant crossed with aninducer in step (a) is a hybrid maize plant produced by crossing maizevariety KDC5164, MIJ6800, MFF7398, or MFX7761 with a different plant.

For examples of the use of double hybrid methods, see Prasanna et al.(eds) Doubled Haploid Technology in Maize Breeding: Theory and PracticeMexico, D.F.: CIMMYT, Barnabus et al. “Colchicine, an efficient genomedoubling agent for maize microsporescultured in anthero”, Plant CellReports, v. 18:858-862, 1999 or US patent application 2003/0005479.Sometimes this doubled haploid can be used as an inbred but sometimes itis further self pollinated to finish the inbred development. Anotherbreeding process is pedigree selection which uses the selection in an F2population produced from a cross of two genotypes (often elite inbredlines), or selection of progeny of synthetic varieties, open pollinated,composite, or backcrossed populations. Pedigree selection is effectivefor highly heritable traits but other traits, such as yield, requirereplicated test crosses at a variety of stages for accurate selection.

The maize variety and hybrid corn lines of the present invention can beemployed in a variety of breeding methods that can be selected,depending on the mode of reproduction, the trait and/or the condition ofthe germplasm. Thus, any breeding methods using the inbred corn lineKDC5164, MIJ6800, MFF7398, or MFX7761 or it progeny are part of thisinvention. Such methods can include, but are not limited to, markerassisted breeding, selection, selfing, backcrossing, hybrid production,and crosses to populations.

All plants and plant cells produced using maize variety KDC5164,MIJ6800, MFF7398, or MFX7761 are encompassed within the presentinvention, which also encompasses the corn variety used in crosses withother, different, corn varieties to produce corn hybrid seeds and hybridplants and the grain produced on the hybrid plant. This inventionincludes progeny plants and plant cells, which upon growth anddifferentiation produce corn plants having the physiological andmorphological characteristics of the maize variety KDC5164, MIJ6800,MFF7398, or MFX7761 when grown in the same environmental conditions.

Maize breeders select for a variety of traits in inbred plants thatimpact hybrid performance in addition to selecting for acceptableparental traits. Such traits include, but are not limited, to yieldpotential in hybrid combination, dry down, maturity, grain moisture atharvest, green snap, resistance to root lodging, resistance to stalklodging, grain quality, disease and insect resistance, ear, and plantheight. Additionally, because hybrid performance may differ in differentsoil types such as those having low levels of organic matter, clay,sand, black, high pH, or low pH; or in different environments such aswet environments, drought environments, and no tillage conditionsmultiple trials testing for agronomic traits must be run to asserthybrid performance across environments. These traits are governed by acomplex genetic system that makes selection and breeding of an inbredline extremely difficult. However, even if an inbred, in hybridcombination, has excellent yield (a desired characteristic), it may notbe useful for hybrid seed production if the inbred lacks acceptableparental traits, for example, seed size, pollen production, good silks,plant height, etc.

The following example is provided to illustrate the difficulty ofbreeding and developing inbred lines. Two inbreds compared forsimilarity of 29 traits differed significantly for 18 traits between thetwo lines. If 18 simply inherited single gene traits were polymorphicwith gene frequencies of 0.5 in the parental lines, and assumingindependent segregation (as would essentially be the case if each traitresided on a different chromosome arm), then the specific combination ofthese traits as embodied in an inbred would only be expected to becomefixed at a rate of one in 262,144 possible homozygous geneticcombinations. Selection of the specific inbred combination is alsoinfluenced by the specific selection environment on many of these 18traits which makes the probability of obtaining this one inbred evenmore remote. In addition, most traits in the corn genome are not singledominant genes; they are multi-genetic with additive gene action but notdominant gene action. Thus, the general approach of producing anon-segregating F1 generation and self pollinating to produce an F2generation that segregates for traits and then selecting progeny fromthe F2 generation with the desired visual traits does not easily lead toa useful inbred. Great care and breeder expertise must be used in theselection of breeding material to continue to increase yield and enhancedesirable agronomic features of inbreds and resultant commercialhybrids.

In one embodiment, a method of producing a plant of this invention is byplanting the seed of KDC5164, MIJ6800, MFF7398, or MFX7761, which issubstantially homozygous, self-pollinating or sib pollinating theresultant plant in isolate environment, and harvesting the resultantseed. The F1 hybrid seed can be produced using two distinct inbreds, themale inbred contributing pollen to the female seed producing parent, thefemale seed producing parent, on the other hand, is not contributingpollen to the seed. Thus, in some embodiments, a method is provided forproducing an hybrid maize seed by crossing a plant of maize varietyKDC5164, MIJ6800, MFF7398, or MFX7761 with a different maize plant(e.g., a different inbred line), and harvesting the resultant hybridmaize seed. A maize plant of the present invention can act as a male orfemale part in hybrid production.

A method is also provided for producing maize seed comprising growingthe plant of this invention until seed is produced and harvesting theseed, wherein the harvested seed is inbred or hybrid or haploid seed.Plants and plant parts produced by the seed of this method is alsoprovided herein. Additionally, provided herein is a method of producinghybrid seed corn from this inbred corn line and producing hybrid plantsand seeds from the hybrid seed corn of this invention.

Thus, in some embodiments, the invention provides hybrid seed, producedby planting, in pollinating proximity, seeds of corn inbred lineKDC5164, MIJ6800, MFF7398, or MFX7761 and seeds of another inbred line.The corn plants resulting from said planting are cultivated;emasculation of one of the inbred lines (i.e., the selected inbredplant) and allowing pollination to occur. Seeds produced by plants ofthe selected inbred can be harvested. In further embodiments, seeds ofcorn inbred line KDC5164, MIJ6800, MFF7398, or MFX7761 are planted andcultivated. Alternatively, emasculated plants are pollinated withpreserved maize pollen (as described in U.S. Pat. No. 5,596,838 toGreaves). The seeds produced by the inbred line KDC5164, MIJ6800,MFF7398, or MFX7761 pollinated with the preserved pollen can beharvested. The hybrid seed produced by the hybrid combination of plantsof inbred corn seed designated KDC5164, MIJ6800, MFF7398, or MFX7761 andplants of another inbred line or produced by the plants of inbred cornseed designated KDC5164, MIJ6800, MFF7398, or MFX7761 pollinated bypreserved pollen are included in the present invention. This inventionfurther encompasses hybrid plants and plant parts thereof including butnot limited to the grain and pollen of the plant grown from this hybridseed.

In two alternative embodiments, the method is provided for producing anhybrid maize seed, the method comprising crossing a plant of maizevariety plant KDC5164, MIJ6800, MFF7398, or MFX7761 with a differentmaize variety (e.g., a different inbred line), wherein the pollen of themaize variety KDC5164, MIJ6800, MFF7398, or MFX7761 pollinates thedifferent maize variety, or in the alternative the pollen of thedifferent maize variety pollinates maize variety KDC5164, MIJ6800,MFF7398, or MFX7761, and the resultant hybrid maize seed is harvested.

In particular embodiments, this invention is directed to the uniquecombination of traits that combine in corn line KDC5164, MIJ6800,MFF7398, or MFX7761. Also encompassed within this invention is an F1hybrid maize seed comprising an inbred maize plant cell of inbred maizeplant KDC5164, MIJ6800, MFF7398, or MFX7761.

The invention further relates to methods for producing other maizebreeding lines derived from the corn inbred of this invention bycrossing the maize inbred plant KDC5164, MIJ6800, MFF7398, or MFX7761with a second maize plant and growing the progeny seed to yield a inbredKDC5164, MIJ6800, MFF7398, or MFX7761-derived maize plant. Thus, in someembodiments of this invention, a method is provided for producing amaize plant derived from the inbred plant KDC5164, MIJ6800, MFF7398, orMFX7761, the method comprising the steps of: (a) growing a hybridprogeny plant wherein the maize variety of this invention is a parent(b) crossing the hybrid progeny plant with itself or a different plantto produce a seed of a progeny plant; (c) growing the progeny plant fromsaid seed and crossing the progeny plant with itself or a differentplant; and (d) repeating steps (c) for an additional generation toproduce a maize plant derived from the inbred plant KDC5164, MIJ6800,MFF7398, or MFX7761. The present invention also provides a maize seedproduced by crossing the plant of this invention with itself or adifferent maize plant.

Thus, other aspects of this invention include a method for developing amaize plant in a maize plant breeding program, comprising applying plantbreeding techniques comprising recurrent selection, backcrossing,pedigree breeding, marker enhanced selection, haploid/double haploidproduction, or transformation to the maize plant of this invention, orits parts, wherein application of said techniques results in developmentof a maize plant.

B. Transfer of Additional Traits into Inbred Corn Line KDC5164, MIJ6800,MFF7398, or MFX7761

A specific location on a chromosome can be referred to as a locus. Traitconversion refers to a variety that has been modified such that thevariety retains its physiological and morphological characteristicsexcept for those changed by the introduction of the trait. Thus avariety undergoing a herbicide resistance trait conversion will evidencethe additional trait of resisting damage by the herbicide. The varietywill after trait conversion have one or more loci with a specificdesired trait. Such a variety modification may be through mutant genes,transgenes, or native traits. A maize line and any minor geneticmodifications which may include a trait conversion, a mutation, or avariant is a variety.

The use of an inbred maize plant, such as the inbred of the presentinvention, as a recurrent parent in a breeding program is referred to asbackcrossing. Backcrossing is often employed to introduce an additionaltrait (e.g., targeted trait or trait of interest) or trait(s), eithertransgenic or nontransgenic, into a recurrent parent. A plant with adesired trait or locus is crossed into a recurrent maize parent usuallyin one or more backcrosses. If markers are employed to assist inselection of progeny that have the desired trait and recurrent parentbackground genetics, then the number of backcrosses needed to recoverthe recurrent parent with the desired trait or locus can be relativelyfew, e.g., two or three. However, 3, 4, 5 or more backcrosses are oftenrequired to produce the desired inbred with the gene or locus conversionin place. The number of backcrosses needed for a trait introduction isoften linked to the genetics of the line carrying the trait and therecurrent parent and the genetics of the trait. Multigenic traits,recessive alleles and unlinked traits can affect the number ofbackcrosses that may be necessary to achieve the desired backcrossconversion of the inbred.

Basic maize crossing techniques, as well as other corn breeding methodsincluding recurrent, bulk or mass selection, pedigree breeding, openpollination breeding, marker assisted selection/breeding, doublehaploids development and selection breeding are well known in the art(see, e.g., Hallauer, Corn and Corn Improvement, Sprague and Dudley, 3rdEd. 1998). Dominant, single gene traits or traits with obviousphenotypic changes are particularly well managed in backcrossingprograms, as are well known in the art. A backcross conversion or locusconversion both refer to a product of a backcrossing program.

A backcrossing program is more complicated when the trait is a recessivegene. A determination of the presence of the recessive gene requires theuse of some testing to determine if the trait has been transferred. Useof markers to detect the gene reduces the complexity of traitidentification in the progeny. A marker specific for a recessive trait,such as a single nucleotide polymorphism (SNP), can increase theefficiency and speed of tracking the recessive trait within abackcrossing program.

The last backcross generation can be selfed, if necessary, to give purebreeding progeny for the nucleic acid(s) being transferred. Theresulting plants generally have essentially all of the morphological andphysiological characteristics of the inbred corn line of interest, inaddition to the transferred trait(s) (e.g., one or more gene traits).The exact backcrossing protocol will depend on the trait being alteredto determine an appropriate testing protocol.

Thus, in some embodiments, one or more additional traits can beintroduced into a plant of this invention using any method known in theart for introducing traits into plants. Nucleotide sequences encodingtraits of interest can all be located at the same genomic locus in thedonor, non-recurrent parent, and in the case of transgenes, can be partof a single DNA construct integrated into the donor's genome or intoadditional chromosomes integrated into the donor's genome.Alternatively, if the nucleotide sequences of interest are located atdifferent genomic loci in the donor, non-recurrent parent, backcrossingcan be carried out to establish all of the morphological andphysiological characteristics of the plant of the invention in additionto the nucleotide sequences encoding the traits of interest in theresulting maize inbred line.

Accordingly, the present invention provides a method of introducing orintrogressing at least one additional trait into the maize inbred lineKDC5164, MIJ6800, MFF7398, or MFX7761, comprising the steps of: (a)crossing a plant grown from the seed of the maize inbred line KDC5164,MIJ6800, MFF7398, or MFX7761 (which is the recurrent parent,representative seed of which has been deposited), with a donor plant ofanother maize line that comprises at least one additional trait toproduce F1 plants; (b) selecting F1 plants having the at least oneadditional trait to produce the selected F1 progeny plants; (c) crossingthe F1 plants of (b) with the recurrent parent to produce backcrossedprogeny plants having the at least one additional trait; (d) selectingfor backcrossed progeny plants that have at least one of the additionaltraits and physiological and morphological characteristics of maizeinbred line of the recurrent parent to produce selected backcrossedprogeny plants; and (e) repeating the crossing of the selectedbackcrossed progeny to the recurrent parent of step (c) and theselecting of step (d) in succession to produce a plant that comprises atleast one additional trait and all of the physiological andmorphological characteristics of the maize inbred line KDC5164, MIJ6800,MFF7398, or MFX7761 when grown in the same environmental conditions(e.g., essentially the recurrent parent having the at least oneadditional trait).

In some embodiments of this invention, the at least one additional traitcomprises the trait of male sterility, herbicide resistance, insectresistance, disease resistance, altered starch, modified amylase starch,amylose starch, waxy starch, or any combination thereof. In otherembodiments of this invention, the at least one desired trait isconferred by a nucleic acid molecule encoding an enzyme that includes,but is not limited to, a phytase, a stearyl-ACP desaturase, afructosyltransferase, a levansucrase, an amylase, an invertase, a starchbranching enzyme, or any combination thereof.

In some embodiments, the selecting and crossing steps of (e) arerepeated at least 3 times in order to produce a plant that comprises theat least one desired trait and all of the physiological andmorphological characteristics of the maize inbred line of the recurrentparent in the present invention (listed in Table 1) when grown under thesame environmental conditions (as determined at the 5% significancelevel). In other embodiments, the selecting and crossing steps of (e)are repeated from 0 to 2 times, from 0 to 3 times, from 0 to 4 times, 0to 5 times, from 0 to 6 times, from 0 to 7 times, from 0 to 8 times,from 0 to 9 times or from 0 to 10 times, in order to produce a plantthat comprises the at least one additional trait and all of thephysiological and morphological characteristics of the maize inbred lineof the recurrent parent in the present invention. In other embodiments,the crossing and growing steps of (a) and (b) in step (c) are repeatedfrom 0 to n times (wherein n can be any number) in order to produce aplant that comprises the at least one additional trait and all of thephysiological and morphological characteristics of the maize inbred lineof the recurrent parent in the present invention.

Another aspect of the invention provides a maize plant havingessentially all the physiological and morphological characteristics ofmaize variety KDC5164, MIJ6800, MFF7398, or MFX7761 and furthercomprising an additional trait, wherein the additional trait is selectedfrom the group consisting of increased water stress resistance, waxystarch, male sterility or restoration of male fertility, modifiedcarbohydrate metabolism, modified protein metabolism, modified fattyacid metabolism, altered starch, thermotolerant amylase, herbicideresistance, insect resistance, nematode resistance, bacterial diseaseresistance, fungal disease resistance, and viral disease resistance. Insome embodiments, the additional trait is conferred by introducing atransgene. Some embodiments of the invention provide a seed produced bythe maize plant having essentially all the physiological andmorphological characteristics of maize variety KDC5164, MIJ6800,MFF7398, or MFX7761 and further comprising an additional trait.

The method of introducing traits as described herein can be done withfewer back crossing events if the trait and/or the genotype of thepresent invention is selected for or identified through the use ofmarkers. SSR, microsatellites, single nucleotide polymorphisms (SNPs)and the like decrease the amount of breeding time required to locate aline with the desired trait or traits and the characteristics of thepresent invention. Backcrossing in two or even three traits (for examplethe glyphosate resistance, Europe corn borer resistance, corn rootwormresistance) is routinely done with the use of marker assisted breedingtechniques and or selection pressure testing. Introduction of transgenesor mutations into a maize line is known as single gene conversion. Morethan one gene and, in particular, transgenes and/or mutations that arereadily tracked with markers, can be moved during the same “single geneconversion” process. This single gene conversion process results in aline comprising more desired or targeted traits than just the one butstill having the characteristics of the plant line of the presentinvention plus those characteristics added by the desired/targetedtraits.

In some aspects, the present invention provides a converted seed, plant,plant part or plant cell of inbred maize variety KDC5164, MIJ6800,MFF7398, or MFX7761, representative seed of the maize variety KDC5164,MIJ6800, MFF7398, or MFX7761 having been deposited, wherein theconverted seed, plant, plant part or plant cell comprises a locusconversion, and wherein the plant or a plant grown from the convertedseed, plant part or plant cell comprises the locus conversion andotherwise comprises the phenotypic characteristics of maize varietyKDC5164, MIJ6800, MFF7398, or MFX7761 listed in Table 1 when grown underthe same environmental conditions.

A locus conversion refers to plants within a variety that have beenmodified in a manner that retains the overall genetics of the varietyand further comprises one or more loci with a specific desired trait,such as male sterility, insect resistance, disease resistance orherbicide tolerance or resistance. Examples of single locus conversionsinclude mutant genes, transgenes and native traits finely mapped to asingle locus. One or more locus conversion traits may be introduced intoa single corn variety.

Genetic variants of inbred corn line KDC5164, MIJ6800, MFF7398, orMFX7761 that are naturally-occurring or created through traditionalbreeding methods using inbred corn line KDC5164, MIJ6800, MFF7398, orMFX7761 are also intended to be within the scope of this invention. Inparticular embodiments, the invention encompasses plants of thisinvention and parts thereof further comprising one or more additionaltraits, in particular, specific, single gene transferred traits.Examples of traits that may be transferred include, but are not limitedto, herbicide resistance, disease resistance (e.g., bacterial, fungal orviral disease), nematode resistance, tolerance to abiotic stresses(e.g., drought, temperature, salinity), yield enhancement, improvednutritional quality (e.g., oil starch and protein content or quality),modified metabolism (e.g. protein, carbohydrates, starch, amylase)altered reproductive capability (e.g., male sterility) or otheragronomically important traits.

One or more new traits can be transferredto a plant of this invention, or, alternatively, one or more traits of aplant of this invention are altered or substituted. The introduction ofthe trait(s) into a plant of this invention may be achieved by anymethod of plant breeding known in the art, for example, pedigreebreeding, backcrossing, doubled-haploid breeding, and the like.

C. Nucleic Acids for Introduction into Maize Plants of the PresentInvention

As would be appreciated by one of skill in the art, any nucleotidesequence of interest can be introduced into the plants and/or partsthereof of the present invention. Some exemplary nucleotide sequencesand traits that may be used with the present invention are providedherein.

Methods and techniques for introducing and/or introgressing a trait ornucleotide sequence into a plant of the present invention throughbreeding, transformation, site specific insertion, mutation and thelike, are well known and understood by those of ordinary skill in theart. Nonlimiting examples of such techniques include, but are notlimited to, anther culturing, haploid/double haploid production,(including, but not limited to, stock six, which is a breeding/selectionmethod using color markers), transformation, irradiation to producemutations, and chemical or biological mutation agents.

1. Male Sterility

As described herein, the inbred and hybrid lines plants of thisinvention can comprise male sterility. Male sterility and/or CMS(cytoplasmic male sterility) systems for maize parallel the CMS typesystems, were first used in maize in the seventies but were to widelyembraced; however, CMS has have been routinely used in hybrid productionin sunflower plants. A number of methods are available to generate malesterile plants including, but not limited to, introduction into theplant of nucleotide sequences that confer male sterility, by chemicals,and/or by a mixture of nucleotide sequences conferring male sterility,natural or induced sterility mutations, and/or chemicals.

As described herein, the inbred and hybrid plants of this invention cancomprise the trait of male sterility. Male sterility is useful, forexample, in hybrid production for elimination of pollen shed from theseed producing parent. Sterility can be produced by pulling or cuttingtassels from the plant, i.e., detasseling, use of gametocides, or use ofgenetic material to render the plant sterile using a CMS type of geneticcontrol or a nuclear genetic sterility, use of chemicals, for exampleherbicides that inhibit or kill pollen. The seed producing parent can begrown in isolation from other pollen sources except for the pollensource which is the male fertile inbred, which serves as the male parentin the hybrid. To facilitate pollination of the seed producing (female)parent, the male fertile inbreds can be planted in rows near the malesterile (female) inbred.

In hybrid seed production using the standard CMS system, three differentmaize lines are employed. The first line is cytoplasmic male-sterile.This line will be the seed producing parent line. The second line is afertile inbred that is the same as or isogenic with the seed producinginbred parent but lacking the trait of male sterility. This is amaintainer line used to make new inbred seed of the seed producing malesterile parent. The third line is a different inbred which is fertile,has normal cytoplasm and carries a fertility restoring gene. This lineis called the restorer line in the CMS system. The CMS cytoplasm isinherited from the maternal parent (or the seed producing plant);therefore in order for the hybrid seed produced on such a plant to befertile, the pollen used to fertilize this plant must carry the restorergene. The positive aspect of this process is that it allows hybrid seedto be produced without the need for detasseling the seed parent.However, this system does require breeding of all three types oflines: 1) a male sterile line-to carry the CMS, 2) a maintainer line;and 3) a line carrying the fertility restorer gene.

Accordingly, in some embodiments of the present invention, sterilehybrids are produced and the pollen necessary for the formation of grainon these hybrids is supplied by interplanting of fertile inbreds in thefield with the sterile hybrids.

A number of additional techniques exist that are designed to avoiddetasseling in maize hybrid production. Nonlimiting examples of suchtechniques include switchable male sterility, lethal genes in the pollenor anther, inducible male sterility and/or male sterility genes withchemical restorers. Additional examples include, but are not limited to,U.S. Pat. No. 6,025,546, which describes the use of tapetum-specificpromoters and the barnase gene to produce male sterility, and U.S. Pat.No. 6,627,799, which describes modifying stamen cells to provide malesterility. Therefore, one aspect of the present invention provides acorn plant of this invention comprising one or more nucleotide sequencesthat restore male fertility to male-sterile maize inbreds or hybridsand/or one or more nucleotide sequences or traits to produce malesterility in maize inbreds or hybrids.

Furthermore, methods for genetic male sterility are disclosed in EPOPublication No. 89/3010153.8, PCT Publication No. WO 90/08828 and U.S.Pat. Nos. 4,654,465, 4,727,219, 3,861,709, 5,432,068 and 3,710,511.Gametocides, some of which are taught in U.S. Pat. No. 4,735,649(incorporated by reference) can be employed to make the plant malesterile. Gametocides, including, but not limited to, glyphosate, and itsderivatives are chemicals or substances that negatively affect thepollen or at least the fertility of the pollen and provide malesterility to the seed producing parent.

It is noted that hybrid production employing any most forms of malesterility including mechanical emasculation can have a small occurrenceof self pollinated female inbred seeds along with the intended F1 hybridseeds. Great measures are taken to avoid the inbred seed production in ahybrid seed production field; but inbred seed can occur during F1 seedproduction and it gets harvested with the hybrid seed harvest.

Inbred seed in a sample of hybrid seed may be detected using molecularmarkers. Alternatively, the seed sample can be planted and an inbredcapture process can be used to isolate inbred seed from the hybrid F1seed sources. The inbred plants tend to be readily distinguished fromthe hybrid plants due to the inbreds having a stunted appearance, i.e.,shorter plant, smaller ear, etc. Self pollination of the stunted plantsgrown from these identified putative inbred plants produces either thefemale inbred seed, if it was an inbred plant or if it was a weak hybridthan the hybrid kernel will be F2 seed. The resultant plants areobserved for size or they can be tested by markers to identify anyinbred plants. The identified inbred plants can be selected andself-pollinated to form the inbred seed.

2. Additional Traits of Interest

As discussed above, backcrossing of recessive traits has allowed knownmutant traits to be moved into elite germplasm. Mutations can beintroduced in germplasm by the plant breeder. Mutations can also resultfrom plant or seed or pollen exposure to temperature alterations,culturing, radiation in various forms, chemical mutagens like EMS andlike, as are well known in the art. Non-limiting examples of mutantgenes that have been identified and introduced into elite maize usefulwith this invention include the genotypes numerous sterility and partialsterility genes, herbicide resistant mutants, phytic acid mutants, waxy(wx), amylose extender (ae), dull (du), horny (h), shrunken (sh),brittle (bt), floury (fl), opaque (o), and sugary (su). Some of thebracketed nomenclature for these mutant genes is based on the effectthese mutant genes have on the physical appearance and phenotype of thekernel.

Additional mutations useful with this invention include, but are notlimited to, those that result in the production of starch with markedlydifferent functional properties even though the phenotypes of the seedand plant remain the same. Such genotypes include, but are not limitedto, sugary-1 (su1), sugary-2 (su2); shrunken 1 (sh1) and shrunken 2(sh2).

Additional, exemplary nucleic acid molecules that can be introduced intoa plant of the present invention include, but are not limited to,nucleotide sequences that confer insect resistance including, but notlimited to, resistance to Corn Rootworm in the event DAS-59122-7, Mir604Modified Cry3A event, Event 5307 Syngenta, MON 89034, MON 88017 Bacillusthuringiensis (Cry genes) Cry34/35Ab1, Cry1A.105, Cry1F, Cry2Ab2, Cry1A,Cry1AB, Cry1Ac Cry3Bb1, or any combination thereof. Thus, for example,in some embodiments, an insecticidal gene that can be introduced into aplant of the present invention is a Cry1Ab gene or a portion thereof,for example, introduced into a plant of the present invention from amaize line comprising a Bt-11 event as described in U.S. Pat. No.6,114,608, (incorporated herein by reference) or from a maize linecomprising a 176 Bt event as described in Koziel et al. (Biotechnology11: 194-200 (1993)).

In other embodiments of this invention, nucleotide sequences that conferdisease resistance are introduced and/or transformed into the inbredline. Non-limiting examples of such nucleotide sequences include, butare not limited to, a nucleotide sequence encoding Mosaic virusresistance, a nucleotide sequence encoding an MDMV strain B coat proteinwhose expression confers resistance to mixed infections of maize dwarfmosaic virus and maize chlorotic mottle virus (Murry et al.Biotechnology (1993) 11:1559-64, a nucleotide sequence conferringresistance to Northern corn leaf blight, and a nucleotide sequenceconferring resistance to Southern corn leaf blight, or any combinationthereof.

In additional embodiments, nucleotide sequences that confer herbicideresistance/tolerance are useful with the present invention, non-limitingexamples of which comprise nucleotide sequences conferring resistance toherbicides for example imazethapyr, glyphosate, dicamba, and the like,and nucleotide sequences encoding Pat(phosphinothricin-N-acetyltransferase), Bar (bialophos), alteredacetohydroxyacid synthase (AHAS) (confers tolerance to variousimidazolinone or sulfonamide herbicides) (U.S. Pat. No. 4,761,373), orany combination thereof.

Additional, non-limiting examples of nucleotide sequences conferringherbicide resistance/tolerance that are useful with the presentinvention, include nucleotide sequences conferring tolerance toimidazolinones (e.g., a “IT” or “IR” trait). U.S. Pat. No. 4,975,374(incorporated herein by reference), relates to plant cells and plantscontaining a gene encoding a mutant glutamine synthetase (GS) havingresistance to inhibition by herbicides that are known to inhibit GS,e.g., phosphinothricin and methionine sulfoximine. Also, expression of aStreptomyces bar gene encoding a phosphinothricin acetyl transferase inmaize plants confers tolerance to the herbicide phosphinothricin orglufosinate (U.S. Pat. No. 5,489,520). U.S. Pat. No. 5,013,659,(incorporated herein by reference), is directed to plants that express amutant acetolactate synthase (ALS) that renders the plants resistant toinhibition by sulfonylurea herbicides. U.S. Pat. No. 5,162,602 disclosesnucleotide sequences that confer resistance to cyclohexanedione andaryloxyphenoxypropanoic acid herbicides. The tolerance is conferred byan altered acetyl coenzyme A carboxylase (ACCase). U.S. Pat. No.5,554,798 discloses transgenic glyphosate tolerant maize plants, whichtolerance is conferred by an altered 5-enolpyruvyl-3-phosphoshikimate(EPSP) synthase gene. U.S. Pat. No. 5,804,425 discloses transgenicglyphosate tolerant maize plants, which tolerance is conferred by anEPSP synthase gene derived from Agrobacterium tumefaciens CP-4 strain.Also, tolerance to a protoporphyrinogen oxidase inhibitor is achieved byexpression of a protoporphyrinogen oxidase enzyme in plants as disclosedin U.S. Pat. Nos. 5,767,373, 6,282,837, or WO 01/12825. Another traittransferable to the plant of the present invention confers a safetyeffect or additional tolerance to an inhibitor of the enzymehydroxyphenylpyruvate dioxygenase (HPPD) and transgenes conferring suchtrait are, for example, described in PCT Publication Nos. WO 9638567, WO9802562, WO 9923886, WO 9925842, WO 9749816, WO 9804685 and WO 9904021.Any of the above described nucleotide sequences identified to conferherbicide resistance/tolerance can be used to confer suchresistance/tolerance to the plants of the present invention. Thesenucleotide sequences can be introduced or transformed into the plants ofthe present invention alone or in any thereof.

Additional embodiments of this present invention include nucleotidesequences conferring altered traits. Such altered traits include, butare not limited to, lignin composition and production (including but notlimited to nucleotide sequences conferring the brown mid-rib trait),flowering, senescence, and the like, or any combination thereof.

The present invention also encompasses methods for the introduction intoa plant of this invention, one or more traits that have an effect onproducts or by-products of the corn plant such as the sugars, oils,protein, ethanol, biomass and the like. Such traits can include thosethat result in the formation of an altered carbohydrate or alteredstarch. An altered carbohydrate or altered starch can be formed as aresult of expression of one or more introduced nucleotide sequences thataffect synthases, branching enzymes, pullanases, debranching enzymes,isoamylases, alpha amylases, beta amylases, AGP, ADP and other enzymeswhich affect amylose and/or amylopectin ratio or content, or thebranching pattern of starch.

Introduced fatty acid modifying nucleotide sequences can also affectstarch content and therefore can be employed in the methods and plantsof this invention. Additionally, introduced nucleotide sequences thatare associated with or affect starch and carbohydrates can be adapted sothat the nucleotide sequence or its enzyme product does not necessarilyalter the form or formation of the starch or carbohydrate of the seed orplant but instead the introduced nucleotide sequence or its RNA,polypeptide, protein or enzyme can be adapted to degrade, alter, orotherwise change the formed starch or carbohydrate. Examples of thistechnology are shown, for example, in U.S. Pat. Nos. 7,033,627,5,714,474, 5,543,570, 5,705,375, 7,102,057, each of which areincorporated by reference. An example of the use of an alpha amylaseadapted in this manner in maize is described in U.S. Pat. No. 7,407,677,the content of which is also incorporated herein by reference.

Additionally, the genes, promoters, transit peptides, targetingsequence and other genetic material used to form these varioustransgenic events can be used in to form a new transgene, promoter,targeting, etc. or to configure a synthetic gene for use intransformation, and after this genetic material is transformed into aline, which is stable. The new event can be backcrossed into germplasmof the present invention.

In some embodiments, a combination of traits can be transformed orintroduced into the plants of the present invention. This in someembodiments, a transgene can be introduced into a plant of a presentinvention which comprises a nucleotide sequence conferring tolerance toa herbicide and at least another nucleotide sequence encoding anothertrait, such as for example, an insecticidal protein. Such a combinationof single traits can be, for example, a Cry1Ab gene and a bar gene. Theintroduction of a Bt11 event into a maize line, such as the line of thepresent invention, by backcrossing is exemplified in U.S. Pat. No.6,114,608, and the present invention includes methods of introducing aBt11 event into a plant of the present invention and to progeny thereofusing, e.g., markers as described in U.S. Pat. No. 6,114,608.

D. Transformation of Corn Inbred KDC5164, MIJ6800, MFF7398, or MFX7761Plants and/or Parts Thereof

The term transgenic plant refers to a plant having one or more geneticsequences that are introduced into the genome of a plant by atransformation method and the progeny thereof. With the advent ofmolecular biological techniques that have allowed the isolation andcharacterization of nucleic acids that encode specific protein products,scientists in the field of plant biology developed a strong interest inengineering the genome of plants to contain and express foreign nucleicacids, or additional, or modified versions of native or endogenousnucleic acids (perhaps driven by different promoters) in order to alterthe traits of a plant in a specific manner. Such foreign, additionaland/or modified nucleic acids are referred to herein collectively as“transgenes.” The term “transgene,” as used herein, is not necessarilyintended to indicate that the foreign nucleic acid is from a differentplant species. For example, the transgene may be a particular allelederived from another corn line or may be an additional copy of anendogenous gene. Over the last twenty to twenty-five years severalmethods for producing transgenic plants have been developed. Therefore,in particular embodiments, the present invention also encompassestransformed plants and/or parts thereof (e.g., cells, seeds, anthers,ovules, and the like) of inbred corn line KDC5164, MIJ6800, MFF7398, orMFX7761.

Transformation methods are techniques for integrating new nucleotidesequence(s) into the genome of a plant by recombinant nucleic acidtechnology, rather than by standard breeding practices. However, once atransgene is introduced into plant material and stably integrated,standard breeding practices can be used to move the transgene into othergermplasm.

Plant transformation generally involves the construction of anexpression vector that will function in plant cells. Such a vectorcomprises DNA or RNA comprising a nucleic acid under control of, oroperatively linked to, a regulatory element (for example, a promoter).The expression vector may contain one or more such operably linkednucleic acid/regulatory element combinations. The vector(s) may be inthe form of, for example, a plasmid or a virus, and can be used, aloneor in combination with other vectors, to provide transformed maizeplants, using transformation methods as described below to incorporatetransgenes into the genetic material of the maize plant(s).

Any transgene(s) known in the art may be introduced into a maize plant,tissue, cell or protoplast according to the present invention, e.g., toimprove commercial or agronomic traits, herbicide resistance, diseaseresistance (e.g., to a bacterial fungal or viral disease), insectresistance, nematode resistance, yield enhancement, nutritional quality(e.g., oil starch and protein content or quality), altered reproductivecapability (e.g., male sterility), and the like or any combinationthereof. Alternatively, a transgene may be introduced for the productionof recombinant proteins (e.g., enzymes) or metabolites.

A recombinant nucleic acid molecule of the invention can be introducedinto a plant cell in a number of art-recognized ways. Suitable methodsof transforming plant cells include microinjection (Crossway et al.BioTechniques 4:320-334 (1986)), electroporation (Riggs et al. Proc.Natl. Acad. Sci. USA 83:5602-5606 (1986)), Agrobacterium-mediatedtransformation (Hinchee et al. Biotechnology 6:915-921 (1988)), directgene transfer (Paszkowski et al. EMBO J. 3:2717-2722 (1984)), ballisticparticle acceleration using devices available, e.g., from Agracetus,Inc., Madison, Wis. and Dupont, Inc., Wilmington, Del. (see, forexample, Sanford et al., U.S. Pat. No. 4,945,050; and McCabe et al.Biotechnology 6:923-926 (1988)), protoplast transformation/regenerationmethods (see U.S. Pat. No. 5,350,689, issued Sep. 27, 1994 to Ciba-GeigyCorp.), Whiskers technology (See U.S. Pat. Nos. 5,464,765 and 5,302,523)and pollen transformation (see U.S. Pat. No. 5,629,183). See alsoWeissinger et al. Annual Rev. Genet. 22:421-477 (1988); Sanford et al.Particulate Science and Technology 5:27-37 (1987) (onion); Christou etal.

A vector or nucleic acid construct of this invention can comprise leadersequences, transit polypeptides, promoters, terminators, genes ornucleotide sequences of interest, introns, nucleotide sequences encodinggenetic markers, etc., and any combination thereof. The nucleotidesequence(s) of the vector or nucleic acid construct can be in sense,antisense, partial antisense, or partial sense orientation in anycombination and multiple gene or nucleotide sequence copies can be used.The transgene or nucleotide sequence can come from a plant as well asfrom a non-plant source (e.g., bacteria, yeast, animals, and viruses)

A vector or nucleic acid construct comprising a transgene that is to beintroduced into a plant of this invention can comprise the transgeneand/or encoding nucleotide sequence under the control of a promoterappropriate for the expression of the transgene and/or nucleotidesequence at the desired time and/or in the desired tissue or part of theplant. Constitutive or inducible promoters can be used, as are wellknown in the art. The vector or nucleic acid construct carrying thetransgene and/or encoding nucleotide sequence can also comprise otherregulatory elements such as, e.g., translation enhancers or terminationsignals. In some embodiments, the transgene or encoding nucleotidesequence is transcribed and translated into a protein. In otherembodiments, the vector or nucleic acid construct can comprise anucleotide sequence that encodes an antisense RNA, a sense RNA that isnot translated or only partially translated, a mRNA, a tRNA, a rRNAand/or a snRNA, as are well known in the art.

In general, methods to transform, modify, edit or alter plant endogenousgenomic DNA include altering the plant native DNA sequence or apre-existing transgenic sequence including regulatory elements, codingand non-coding sequences. These methods can be used, for example, totarget nucleic acids to pre-engineered target recognition sequences inthe genome. Such pre-engineered target sequences may be introduced bygenome editing or modification. As an example, a genetically modifiedplant variety is generated using “custom” or engineered endonucleasessuch as meganucleases produced to modify plant genomes (see e.g., WO2009/114321; Gao et al. (2010) Plant Journal 1:176-187). Anothersite-directed engineering method is through the use of zinc fingerdomain recognition coupled with the restriction properties ofrestriction enzyme. See e.g., Urnov, et al., (2010) Nat Rev Genet.11(9):636-46; Shukla, et al., (2009) Nature 459 (7245):437-41. Atranscription activator-like (TAL) effector-DNA modifying enzyme (TALEor TALEN) is also used to engineer changes in plant genome. See e.g.,US20110145940, Cermak et al., (2011) Nucleic Acids Res. 39(12) and Bochet al., (2009), Science 326(5959): 1509-12. Site-specific modificationof plant genomes can also be performed using the bacterial type IICRISPR (clustered regularly interspaced short palindromic repeats)/Cas(CRISPR-associated) system. See e.g., Belhaj et al., (2013), PlantMethods 9: 39; The Cas9/guide RNA-based system allows targeted cleavageof genomic DNA guided by a customizable small noncoding RNA in plants.

E. Plant Tissue Culture and Regeneration

Plant cells, which have been transformed by any method known in the art,can also be regenerated to produce intact plants using known techniques.Plant regeneration from cultured protoplasts is described in Evans etal., Handbook of Plant Cell Cultures, Vol. 1: (MacMilan Publishing Co.New York, 1983); and Vasil I. R. (ed.), Cell Culture and Somatic CellGenetics of Plants, Acad. Press, Orlando, Vol. I, 1984, and Vol. II,1986). It is known that practically all plants can be regenerated fromcultured cells or tissues.

Means for regeneration vary from species to species of plants, butgenerally a suspension of transformed protoplasts or a petri platecontaining transformed explants is first provided. Callus tissue isformed and shoots may be induced from callus and subsequently root.Alternatively, somatic embryo formation can be induced in the callustissue. These somatic embryos germinate as natural embryos to formplants. The culture media will generally contain various amino acids andplant hormones, such as auxin and cytokinins. A large number of plantshave been shown capable of regeneration from transformed individualcells to obtain transgenic whole plants. Patents and patent publicationscited as exemplary for the processes for transforming plant cells andregenerating plants are the following: U.S. Pat. Nos. 4,459,355,4,536,475, 5,464,763, 5,177,010, 5,187,073, 4,945,050, 5,036,006,5,100,792, 5,371,014, 5,478,744, 5,179,022, 5,565,346, 5,484,956,5,508,468, 5,538,877, 5,554,798, 5,489,520, 5,510,318, 5,204,253 and5,405,765; European Patent Nos. EP 267,159, EP 604 662, EP 672 752, EP442 174, EP 486 233, EP 486 234, EP 539 563 and EP 674 725, and PCTPublication Nos. WO 91/02071 and WO 95/06128.

The use of pollen, cotyledons, zygotic embryos, meristems and ovum asthe target tissue for transformation can eliminate or minimize the needfor extensive tissue culture work. Generally, cells derived frommeristematic tissue are useful. The method of transformation ofmeristematic cells of cereal is taught in PCT Publication No.WO96/04392. Any number of various cell lines, tissues, calli and plantparts can and have been transformed by those having knowledge in theart. Methods of preparing callus or protoplasts from various plants arewell known in the art. Cultures can be initiated from most of theabove-identified tissues. The only requirement of the plant material tobe transformed is that it can ultimately be used to produce atransformed plant.

In Duncan et al. (Planta 165:322-332 (1985)) studies were conducted thatdemonstrated that 97% of plants cultured that produced callus werecapable of plant regeneration. Subsequent experiments with both inbredsand hybrids showed that 91 appeared capable of producing regenerablecallus. In a further study (Songstad et al. Plant Cell Reports 7:262-265(1988)), several media additions were identified that enhancedregenerability of callus of two inbred lines. Other published reportsindicated that “nontraditional” tissues are capable of producing somaticembryogenesis and plant regeneration. Rao et al. (Maize GeneticsCooperation Newsletter 60:64-65 (1986)) describes somatic embryogenesisfrom glume callus cultures and Conger et al. (Plant Cell Reports6:345-347 (1987)) describes somatic embryogenesis from the tissuecultures of maize leaf segments. Thus, it is clear from the literaturethat the state of the art is such that these methods of obtaining plantsfrom callus are, and were, “conventional” in the sense that they areroutinely used and have a very high rate of success.

Tissue culture procedures of maize are described in Green and Rhodes(“Plant Regeneration in Tissue Culture of Maize” in Maize for BiologicalResearch (Plant Molecular Biology Association, Charlottesville, Va. at367 372 (1987)) and in Duncan, et al. (“The Production of Callus Capableof Plant Regeneration from Immature Embryos of Numerous Zea maysGenotypes” Planta 165: 322-332 (1985)). Thus, another aspect of thisinvention is to provide cells that upon growth and differentiationproduce maize plants having the physiological and morphologicalcharacteristics of the plants of the present invention.

G. Genotyping and Genetic Marker Profiles

A number of well known methods can be employed to identify the genotypeof a maize plant. One of the oldest methods is the use of isozymes,which provides a generalized footprint of the genetic material. Otherapproaches adapted to provide a higher definition profile includerestriction fragment length polymorphisms (RFLPs), amplified fragmentlength polymorphisms (AFLPs), random amplified polymorphic DNAs (RAPDs),amplification methods such as the polymerase chain reaction (PCR), whichcan employ different types of primers or probes, microsatellites (SSRs),single nucleotide polymorphisms (SNPs), sequence selection markers, etc.as are well known in the art and can be found in standard textbooks suchas Breeding Field Crops, Milton et. al. Iowa State University Press andGenetic Mapping and Marker Assisted Selection: Basics, Practice andBenefits, N. Manikanda Boopathi Springer India 2013.

The marker profile of the inbred of this invention should be close tohomozygous for alleles. A marker profile produced with any of the locusidentifying systems known in the industry will identify a particularallele at a particular locus. An F1 hybrid made from the inbred of thisinvention will comprise a marker profile of the sum of both of theprofiles of its inbred parents. At each locus, the allele for the inbredof the present invention and the allele for the other inbred parentshould be present. Thus the profile of the inbred of the presentinvention allows for identification of hybrids as containing the inbredparent of the present invention. To identify the female portion of anyhybrid, the hybrid seed material from the pericarp, which is maternallyinherited, is employed in a marker technique. The resultant profile,therefore, is of the maternal parent. A comparison of this maternalprofile with the hybrid profile will allow the identification of thepaternal profile. Accordingly, some embodiments of the present inventionprovide an inbred or hybrid plant, plant part thereof, including but notlimited to a seed or an embryo, and/or a cell thereof having the allelemarker profile of the inbred plant of the this invention, KDC5164,MIJ6800, MFF7398, or MFX7761.

Marker profiles of plants of this invention can be employed to identifyessentially derived varieties or progeny developed with the inbred inits ancestry. The progeny of the inbred line of this invention, KDC5164,MIJ6800, MFF7398, or MFX7761, can be identified by identifying in theprogeny the molecular marker profile of the inbred line KDC5164,MIJ6800, MFF7398, or MFX7761, as measured by either percent identity orpercent similarity.

Different nucleotide sequences or polypeptide sequences having homologyare referred to herein as “homologues.” The term homologue includeshomologous sequences from the same and other species and orthologoussequences from the same and other species. “Homology” refers to thelevel of similarity between two or more nucleotide sequences and/oramino acid sequences in terms of percent of positional identity (i.e.,sequence similarity or identity). Therefore, as used herein “sequenceidentity” refers to the extent to which two optimally alignedpolynucleotide or polypeptide sequences are invariant throughout awindow of alignment of components, e.g., nucleotides or amino acids.“Identity” can be readily calculated by known methods including, but notlimited to, those described in: Computational Molecular Biology (Lesk,A. M., ed.) Oxford University Press, New York (1988); Biocomputing:Informatics and Genome Projects (Smith, D. W., ed.) Academic Press, NewYork (1993); Computer Analysis of Sequence Data, Part I (Griffin, A. M.,and Griffin, H. G., eds.) Humana Press, New Jersey (1994); SequenceAnalysis in Molecular Biology (von Heinje, G., ed.) Academic Press(1987); and Sequence Analysis Primer (Gribskov, M. and Devereux, J.,eds.) Stockton Press, New York (1991).

As described herein, marker systems are not just useful foridentification of the plants of this invention, but can also be used forbreeding and trait conversion techniques. Polymorphisms in maize permitthe use of markers for linkage analysis. If SSR are employed withflanking primers, the marker profile can be developed with PCR, andtherefore Southern blots can often be eliminated. Use of flankingmarkers, PCR and amplification to genotype maize is well known in theart. Primer sequences for SSR markers and maize genome mappinginformation are publicly available on the USDA website at the MaizeGenomics and Genetic Database (Maize GDB).

I. Maize as Human Food and Livestock Feed

Maize is used as human food, livestock feed and as raw material inindustry. Sweet corn kernels having a relative moisture of approximately72% are consumed by humans and may be processed by canning or freezing.The food uses of maize, in addition to human consumption of maizekernels, include both products of dry- and wet-milling industries. Theprincipal products of maize dry milling are grits, meal and flour. Themaize wet-milling industry can provide maize starch, maize syrups anddextrose for food use. Maize oil is recovered from maize germ, which isa by-product of both dry- and wet-milling industries.

Thisgrain is a commodity plant product as are the protein concentrate,protein isolate, starch, meal, flour or oil. A number of differentindustrial processes can be employed to extract or utilize these plantproducts, as are well known in the art.

Maize, including both grain and non-grain portions of the plant, is alsoused extensively as livestock feed, primarily for beef cattle, dairycattle, hogs, and poultry. Industrial uses of maize include productionof ethanol, maize starch in the wet-milling industry and maize flour inthe dry-milling industry. The industrial applications of maize starchand flour are based on functional properties, such as viscosity, filmformation, adhesive properties and ability to suspend particles. Themaize starch and flour have application in the paper and textileindustries. Other industrial uses include applications in adhesives,building materials, foundry binders, laundry starches, explosives,oil-well muds, and other mining applications. Plant parts other than thegrain of maize are also used in industry: for example, stalks and husksare made into paper and wallboard and cobs are used for fuel and to makecharcoal.

The seed of the plant of the present invention can further comprise oneor more single gene traits. The plant produced from the inbred seed ofthe maize line KDC5164, MIJ6800, MFF7398, or MFX7761, the hybrid maizeplant produced from the crossing of said inbred, hybrid seed and variousparts of the hybrid maize plant, can be utilized for human food,livestock feed, and as a raw material in industry.

The General Combining Ability Table shows the GCA (General CombiningAbility) estimates of KDC5164, MIJ6800, MFF7398, or MFX7761 comparedwith the GCA estimates of the other inbreds. The estimates show thegeneral combining ability is weighted by the number ofexperiment/location combinations in which the specific hybridcombination occurs. The interpretation of the data for all traits isthat a positive comparison is a practical advantage. A negativecomparison is a practical disadvantage. The general combining ability ofan inbred is clearly evidenced by the results of the general combiningability estimates. This data compares the inbred parent in a number ofhybrid combinations to a group of “checks”. The check data is from ourcompany's and other companies' hybrids which are commercial products andpre-commercial hybrids, which were grown in the same sets and locations.
